  • 주로 작은 침샘에서 발생하는 샘낭암종의 치료 방침은 수술과 수술 후 보조적 방사선치료가 주로 행해져 왔다. 그러나 설근부에 발생한 샘낭암종에 대해서는 수술적 치료가 가져오는 삶의 질의 저하가 크기 때문에 수술적 치료를 적용하기 쉽지 않다. 또한 샘낭암종의 치료에 있어서 항암제의 역할이 거의 없는 상황에서 방사선치료가 중요한 역할을 할 수 있겠다. 이에 본 저자들은 설근부에 발생한 샘낭암종 세 증례의 방사선치료 결과를 보고 하며 샘낭암종의 치료에 대해서 문헌고찰을 통해 논의하고자 한다.

  • Objectives: To document the incidence and pattern of c-kit protein expression & mutation in adenoid cystic carcinomas. Materials and Methods: Twenty-five cases of adenoid cystic carcinomas of the major and minor salivary glands and the upper and lower respiratory tract were subjected to the immunohistochemical study for ckit(CD117 ; Dako). Nineteen cases of them were analyzed for mutations in exon 11 and exon 17 by PCR-SSCP, and in cases of need, by DNA sequencing. Results: Twenty-three cases (92%) showed c-kit expression, but none showed mutations in exon 11 and exon 17. The expression was restricted to the inner luminal cells in all tubular types and most of cribriform adenoid cystic carcinomas, while the staining was diffuse in all solid variants and two cribriform types. Conclusion: C-kit expression was common in adenoid cystic carcinomas, regardless of their origins. Although genetic bases await further studies, a clinical trial of tyrosine kinase inhibitors in adenoid cystic carcinomas, especially in solid variants, is considered encouraging.
